~6 miles @ ~11.1 min/mi

As we start, the car thermometer registers a brisk 27°F — it's a balmy 29 when we stop. Barry Smith, Rebecca Rosenberg, and Ken Swab lead me limping (tight right hamstring after yesterday's race) along Rock Creek Trail, with a digression to Ken-Gar for hillwork. Four big deer stare at us along the way. RacePacket sets up for a frigid 5k, and we pose by the clock at the finish line. Garmin and Runkeeper show time and distance trackfiles.
